PIN-INSERTING TOOL.

Application filed March 7, 1922.

To all whom t may concern Be it known that I, DANIEL A. CRAUN, a citizen of the United States, residing at Orange, in the county of Orange and State of Virginia, have invented certain new and useful Improvements in Pin-Inserting Tools, of which the following is a specification.

My invention relates to an improvement in pin inserting tools.

In some automobiles, especially the Ford, much diiliculty is encountered in inserting the pin in the valve-stem, owing to its rather inaccessible location, and, besides this, difficulties are presented in inserting this pin just the right distance.

It is the object of this invention to overcome those difficulties successfully.

My present invention consists of a tube and a rod slidable therein, with means for gauging the extent of projection of the rod to correspond to the size of pin to be inserted in the valve-stem.

In the accompanying drawings:

Fig. 1 is a section showing the parts in their normal position, with the pin inserted in the end of the tool;

Fig. 2 shows the position of parts when the pin has been properly inserted in the valve-stem.

A, represents the tube, and 1 is the rod fitted to and slidable in the bore of the tube. This rod has a handle 2 secured to one end, and a spring 3 sleeved around the stem of the handle presses outwardly normally to withdraw the rod l to its normal position, as shown in Fig. 1. I/Vhen so withdrawn, it forms a socket at the end of the tool to receive the major portion of the pin 4, with one end slightly protruding. This facilitates inserting the pin in the hole 5 of the valve-stem 6.

In inserting the pin, the head 7 on the end of the handle is placed in the bottom of the hand, and the first two ngers grasp the fiange 8 of the sleeve 9.

Serial No. 541,718.

The tool is then aimed so that the protruding end of the pin 4 is inserted in the hole 5 of the valve stem, whereupon the operator presses against the head 7, pressing the spring 3 and forcing the rod l through the tube just the correct distance to insert the pin 4, so that the opposite ends project an equal distance beyond the sides of the valvestem.

To gauge accurately the inserting of the pin as above explained, a threaded nipple 10 screws into the threads 11 of the sleeve 9. In the drawing, this is shown screwed into the sleeve its full length, and the shank of theV handle in Fig. 2 is sho-wn pushed in as far'as it will go; but, should the pin be of greater length, the parts are adjusted thereto by turning the threaded nipple 10 to thek left, 'or unscrewing it part way, or in other words a distance corresponding with the length of the pin. For different sized pins, a different size tool is employed, but the parts may be all precisely the saine, except in size.

In this way, a very simple tool for a specialy purpose is provided, thus saving much time, annoyance, and expense hitherto encountered in inserting the pin in the valvesteam.

, I claim:

1. A tool of the character described, including a tube, a rod slidable therein, and a threaded nipple serving as a gauge to regulate and determine the extent of slide of the rod.

2. A tool of the character described, including a tube, a rod slidable therein, a threaded nipple serving as a gauge t0 regulate and determine the extent of slide of the rod, and a spring which, when released, returns the rod to its normal position in the tube.

In testimony whereof I aiiix my signature.

DANIEL A. CRAUN.
